Microsoft E16-4ds v4 Azure VM Reservation

Apply Azure Reserved Instance pricing to eligible E16-4ds v4 compute consumption in the US West 2 region. Microsoft DZH318Z0CSHK-01B3 corresponds to the EDSv4 virtual machine series and the constrained-core E16-4ds v4 size. It is intended for Azure environments where a defined VM family, size, and regional deployment location must match the reservation. The E16-4ds v4 configuration activates 4 vCPUs while retaining 128 GiB of memory from the E16 size. That ratio is relevant for workloads constrained by memory capacity rather than processor throughput, including large in-memory application tiers, data services, and virtualized server roles with substantial memory allocations. The constrained-core designation differentiates this configuration from a full-core E16 deployment. The EDSv4 naming also indicates local temporary disk support and Premium SSD capability. These characteristics help place the VM size within Azure storage-aware application designs, where temporary data can use local disk while persistent workloads can use Premium SSD-backed storage. Match the reservation to eligible E16-4ds v4 usage in US West 2 to apply its reserved-instance pricing benefit.
